LinuxQuestions.org - [SOLVED] error in making avogadro-1.1.1

Hi,

I am installing a package called avogado from here:

http://sourceforge.net/projects/avogadro/?source=typ_redirect

But, when I execute "make -j2" I receive the following error:

Quote:

I couldn't find what package is missing. I'd be grateful to receive your kind helps.
